I am having difficulty with the MS Outlook 2007 journal function.

With my previous version of MS Outlook (2003), I came to rely on the Journal
function as a way to keep track of when and for how long I worked on various
documents/projects. When I wanted to go back and see what documents I worked
on say, a week ago, I could simply click the "journal" function of outlook,
select the day, and I could see icons representing the documents I had opened
that day along with a bar/graph showing how long and when during the day I
worked on the document. This refreshed my memory and allowed me to keep
track of my billable time very easily.

I recently switched from a desktop PC that was networked into a server at
the office full time to a notebook PC that backs up to my firm's server when
I am using the laptop in conjunction with a docking station. The new PC has
Outlook 2007, but the Journal is not recording all the MS Office documents
that I access/edit. It only seems to record the few times I create a new
document using an Office template. I have tried to enable the Journal by
selecting "Tools" "Options" and then ticking the boxes for MS Word, MS Excel
and MS Power Point under the "journal options" menu but this isn't working.
Does the journal need to be configured to look for (or record) the open files
from a different location? HELP! I WANT MY JOURNAL BACK!
